Here's my Audi 200 Turbo Quattro. I bought it for $2000, quite a steal. Since then I've done a few minor things to make it more appealing. The windows were tinted to set off the blacked out look.

I followed them up with 18" ASA wheels. I had to slam the car down, so I got all new intrax springs, and bilstein shocks and struts.
The new suspension feels amazing, and it looks real nice dropped. I then ordered Euro black out tails from Custom Auto Craft in Germany. I had to mod the taillights to get the license plate to fit, but I think they look the best out of everything.
Next I put a straight-back from headers magnaflow exhaust system. This this is louder than some V8's I've owned!
I don't have the pictures up yet, but I have 2 12" subs in the back, with a 2000 watt amp. It's a nice custom installation I'll put up later. I also have a JVC DVD player in the Dash, real nice.
